Female Urinary Incontinence
Female urinary incontinence is approached by classifying the type — stress, urge (OAB), mixed, or overflow/functional — after excluding reversible causes (UTI, high residual), then treating conservatively first (pelvic floor training, lifestyle) and escalating by type.
The big picture
Continence depends on a competent urethral sphincter and a stable, compliant bladder. Stress urinary incontinence (SUI) is leakage with effort/coughing from sphincter/support weakness; urgency urinary incontinence (UUI, part of overactive bladder) is leakage with urgency from detrusor overactivity; mixed incontinence has both; overflow and functional incontinence are separate mechanisms. Reversible contributors (UTI, medications, constipation, high post-void residual) must be excluded.
Classify the type (stress/urge/mixed/overflow) after excluding reversible causes; conservative therapy first, then escalate by type — urodynamics for complex/uncertain cases or before surgery.
Red flags
Exclude infection and a high post-void residual (overflow) before labelling and operating.
Stress, urge, mixed and overflow are managed differently — classify first.
Use urodynamics for mixed/uncertain pictures or prior failed treatment before operating.

Treatment ladder
Treat reversible causes, start conservative therapy for all, and escalate by incontinence type.
Complications
- Skin breakdown, social/psychological impact, falls (nocturia)
- Antimuscarinic side effects/retention
- Sling complications (retention, mesh-related issues, pain)
- Botulinum toxin: retention/need for self-catheterisation
- Correct classification; conservative first; careful patient selection/counselling for surgery
- Adjust therapy; manage retention/sling complications
Summary tables
Female incontinence by type
| Type | Hallmark | First-line treatment |
|---|---|---|
| Stress (SUI) | Leak on cough/effort | Pelvic floor training → midurethral sling |
| Urge (UUI/OAB) | Urgency ± urge leakage | Bladder training + antimuscarinic/beta-3 |
| Mixed | Both stress and urge | Treat the predominant component first |
| Overflow | High residual/retention | Exclude/treat the cause (not a sling) |
Memory hooks
Classify: stress / urge / mixed / overflow.
Exclude UTI and high residual first.
Conservative therapy for all (PFMT, lifestyle).
SUI → sling; urge/OAB → antimuscarinic/beta-3.
Urodynamics for complex/pre-surgery.
Board traps
Exclude UTI/overflow before labelling incontinence.
Conservative first; SUI → sling; OAB → antimuscarinic/beta-3.
Urodynamics for complex/mixed/pre-surgical cases.
Clinical cases
A 55-year-old woman leaks urine when she coughs and exercises, with no urgency. Urinalysis is negative and post-void residual is normal.
